Image in Adaptive card inside Action.ShowCard button in showing undefined

Question

I have designed an Adaptive card and it is rendering fine. I also have a
Action.ShowCard
type button which also has an Adaptive card. Any image in the main card is showing perfectly but if I place any image in the Adaptive card of the
Action.ShowCard
it is rendering like this

The image shows as undefined. Also in the HTML the image tag has no
src

Info

• The image url is public and is showing perfectly in the main card but not in the show card
• I tested it using the
  App Studio's UI Tool
  and it is also giving the same error {
